Hi Barry - if you really want up market then the only place to look is the new Las Colinas de Campoamor resort which is only 10 minutes drive from Villamartin, but is totally in a class of it's own. It is the best resort in the area - not cheap, but it has an exclusive beach club, gym, kids club, tennis, etc, etc and is breathtakingly beautiful.
Even if you decide not to buy or rent there, it is also a great place for lunch!
